ASSIGNOR TO THE BRADT COMPANY, OF NEW BRITAIN, CONNECTICUT, A

CABLE SUPPORT.

Application filed July 23,

I To all whom it may concern:

of a support in the nature of Be it known that LIIERBERTO. ROCK- W LL, a citizen of the United States, and a residentof New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in a Cable Support, of which the following is a specification.

The object of the invention is to produce a cable support having features of novelty and;advantage. Supports of this sort are designed particularly for use with flexible cables and to permit of readily drawing a cable through the support or of readily attaching the support to a cable already strung, and are preferably equipped with a roll support in the nature of a grooved wheel of insulating material to permit free movement of the cable. These, supports are intended for attachment to sides of buildings, to poles, rafters, etc, by means a lag screw. In the present invention the holder itself is readily separated from the lag screw and provision is made for the use of the 0rdinary lag screws as on the market, means being provided for permitting the attachment of the holder to the supporting screw.

In the accompanying drawin Fig.1 is a sideview of the holder shown lace, ig. 2 is an end view of the same, and Fig. 3 is a detail view of the holder proper removed from the supporting lag screw and showing the method of connecting the two parts, i. e., the holderand lag screw. Referring to the drawings, (1 denotes a lag screw of the ordinary type readily found on the market and which, as shown, usually has a square head. I) is a clip aper+ tured to receive the lag screw and with its two ends folded up against the square head of the lag screw in such a manner that the lag screw does not turn in the clip. The ends 0 of the clips which project beyond are customarily found 1921. Serial No, 486,945.

the head oflthe lag screw are bent into con tact to receive the arms of the holder in dieated generally at c. This holder comprises a spindle 5 upon which is mounted a groove wheel 6 of insulating material and on the projecting ends of the spindle are rotatably mountedthe complementary arms 7,17, with oppositely inturned ends 8 8, w

in Figure 1.

The holder can be readily disassembled from the lag screw clip by tilting it to one side' and passing it through the aperture until one of the arms 7 can I then .by tilting it in the opposite direction until the other arm 7 is disengaged. By the use of the clip I) an ordinary lagscrew can be utilized. The clip can be used either for the application of a wrench or some other convenient means for positioning the lag screw in the support, and the aperture in the projecting contacting ends provides the means to receive and retain the holder.

I claim as my invention- In a device of the character described, a lap; Screw with an angular head, a clip apertured to receive said lag screw and fitting be disengaged,

against the outer side of the head, said clip thenbeing bent against opposite sides of the head to prevent relative rotation therebetween, the ends of said clip projecting beyond said head and being bent into contact and apertured, and a holder comprising a spindle, an insulating roller mounted thereon, arms, at. least one of whichis rotatably mounted, at either end of the spindle .at either side of said roller, said arms having complementary hooked shaped ends adaptedto be passed through the apertures.

on the end of said cli to be moved to over ping position to. form a loop to suppor the ends of said spindle from said clip.
